    génération d'au moins un mot aléatoire (AL) dans ledit décodeur (6) ;
    transmission dudit mot aléatoire (AL) audit élément de sécurité (1);
    chiffrement, dans ledit élément de sécurité (1), dudit mot aléatoire (AL) en utilisant une troisième clé (K1) de façon à générer une première clé ;
    chiffrement dans ledit élément de sécurité (1) des données issues du désembrouilleur en utilisant la première clé ;
    transmission des données chiffrées au décodeur (6) ;
    chiffrement, dans ledit décodeur (6), dudit mot aléatoire (AL) en utilisant la troisième clé (K1) de façon à générer une seconde clé ; et
    déchiffrement dans ledit décodeur (6) desdites données chiffrées issues de l'élément de sécurité en utilisant la seconde clé.
  2. Procédé selon la revendication 1, dans lequel l'étape de génération de ladite première clé et l'étape de génération de ladite seconde clé sont renouvelées à chaque session ou plusieurs fois par session.
  3. Procédé selon la revendication 1, dans lequel la troisième clé est spécifique à la paire élément de sécurité/décodeur.
  4. Elément de sécurité (1) contenant un désembrouilleur (3) pour désembrouiller, sous l'action de mots de contrôle (CWi), des données reçues par l'élément de sécurité, lesdites données représentant au moins un programme embrouillé, caractérisé en ce que ledit élément de sécurité comprend :
    un dispositif (13) pour générer une première clé de chiffrement sous l'action d'un mot aléatoire (AL) et d'une troisième clé (K1) et ;
    un dispositif (10) pour chiffrer les données désembrouillées issues du désembrouilleur (3) en utilisant la première clé de chiffrement.
  5. Décodeur (6) pour décoder des données issues d'un élément de sécurité (1), lesdites données représentant au moins un programme sélectionné par un utilisateur d'un système à accès conditionnel, caractérisé en ce qu'il comprend
    un générateur (11) de mots aléatoires pour générer au moins un mot aléatoire (AL) ;
    un dispositif (12) pour générer une clé de déchiffrement à partir du mot aléatoire ainsi généré et d'une troisième clé (K1) et ;
    un dispositif de déchiffrement (9) pour déchiffrer, sous l'action de la clé de chiffrement, les données issues de l'élément de sécurité, lesdites données étant au préalable désembrouillées et chiffrées sous l'action d'une première clé.
